As the other poster said, the 7104 was introduced later than the 7904.
Tektronix on the website said: 7904(A) 1974, 7104 1978.
BTW: The 7904 is inside (circuit layout, etc.) basically a 7104, but
without an MCP crt.
AFAIK Jim Yanik mentioned this once.
Seems pretty correct to me: My 7904 displays nicely the 1,04 GHz of my
R&S signal generator.
Model numbers nomenclature:
first: always 7 == 7000 series
secound: is BW, 1 = 1000 MHz , 9= 500 mHz, 8= 400 MHz, 7= 200/250
MHz, 5 and 6: 100 MHz (7603 !!) , 4 and 3 = low BW appr. 65 MHz.
series
Pls. don't ask me why: I could not figure out the basic idea behind
this, but after checking all literature I have, that's it.
third: Type of dsiplay/storage: 0 == non storage, 1= storage CRT,
2=improved storage, 3= high writing rate storage, 4= dual beam
(two-gun crt), 5= digital storage
fourth: number of compartments for plug-ins, range I found is 2, 3, 4
.
The "2" I found only in the 7912 (digitizer model wit ha kind of
analogue storage crt and and a complex ciruitry for getting the data
out, very tricky made).
"3" is well known to most of us: e.g. 7603.
"4" are all the major laboratory scopes known for: 7104, 7904, 7704(A)
just my two cents..

No,the 7904A is comparable to the 7104.The earlier 7904 *non-A* had"Funky" <hello@hello.com> wrote in message

No,there was a 7504 that had bistable storage,a real piece of crap,too.Seems pretty correct to me: My 7904 displays nicely the 1,04 GHz of my

Those were the days !
Still not bad going, for a single shot. My TDS8001 has 25- and 50-GHz

its built-in image intensifier.
